Read the FAQ below for more information. + + + API BREAKING CHANGES + ==================== + + Occasionally introducing changes that are breaking the API. The breakage are generally minor and easy to fix. + Here is a change-log of API breaking changes, if you are using one of the functions listed, expect to have to fix some code. + Also read releases logs https://github.com/ocornut/imgui/releases for more details. + + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you. + However if your TitleBg/TitleBgActive alpha was <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color. + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) + { + float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; + return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); + } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDraw::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + became: + ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + argument 'cmd_lists' -> 'draw_data->CmdLists' + argument 'cmd_lists_count' -> 'draw_data->CmdListsCount' + ImDrawList 'commands' -> 'CmdBuffer' + ImDrawList 'vtx_buffer' -> 'VtxBuffer' + ImDrawList n/a -> 'IdxBuffer' (new) + ImDrawCmd 'vtx_count' -> 'ElemCount' + ImDrawCmd 'clip_rect' -> 'ClipRect' + ImDrawCmd 'user_callback' -> 'UserCallback' + ImDrawCmd 'texture_id' -> 'TextureId' + - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. + - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! + - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. + - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). + - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. + - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence + - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry! + - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). + - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). + - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. + - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. + - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). + - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. + - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API + - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. + - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. + - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect().

Convince your company to become a Patron or provide serious funding for development time. + + Q: How do I update to a newer version of ImGui? + A: Overwrite the following files: + imgui.cpp + imgui.h + imgui_demo.cpp + imgui_draw.cpp + imgui_internal.h + stb_rect_pack.h + stb_textedit.h + stb_truetype.h + Don't overwrite imconfig.h if you have made modification to your copy. + Check the "API BREAKING CHANGES" sections for a list of occasional API breaking changes. If you have a problem with a function, search for its name + in the code, there will likely be a comment about it. Please report any issue to the GitHub page! + + Q: What is ImTextureID and how do I display an image? + A: ImTextureID is a void* used to pass renderer-agnostic texture references around until it hits your render function. + ImGui knows nothing about what those bits represent, it just passes them around. It is up to you to decide what you want the void* to carry! + It could be an identifier to your OpenGL texture (cast GLuint to void*), a pointer to your custom engine material (cast MyMaterial* to void*), etc. + At the end of the chain, your renderer takes this void* to cast it back into whatever it needs to select a current texture to render. + Refer to examples applications, where each renderer (in a imgui_impl_xxxx.cpp file) is treating ImTextureID as a different thing. + (c++ tip: OpenGL uses integers to identify textures. You can safely store an integer into a void*, just cast it to void*, don't take it's address!) + To display a custom image/texture within an ImGui window, you may use ImGui::Image(), ImGui::ImageButton(), ImDrawList::AddImage() functions. + ImGui will generate the geometry and draw calls using the ImTextureID that you passed and which your renderer can use. + It is your responsibility to get textures uploaded to your GPU. + + Q: I integrated ImGui in my engine and the text or lines are blurry.. + A: In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f). + Also make sure your orthographic projection matrix and io.DisplaySize matches your actual framebuffer dimension. + + Q: I integrated ImGui in my engine and some elements are clipping or disappearing when I move windows around.. + A: Most likely you are mishandling the clipping rectangles in your render function. Rectangles provided by ImGui are defined as (x1=left,y1=top,x2=right,y2=bottom) and NOT as (x1,y1,width,height). + + Q: Can I have multiple widgets with the same label? Can I have widget without a label? (Yes) + A: Yes. A primer on the use of labels/IDs in ImGui.. + + - Elements that are not clickable, such as Text() items don't need an ID. + + - Interactive widgets require state to be carried over multiple frames (most typically ImGui often needs to remember what is the "active" widget). + to do so they need a unique ID. unique ID are typically derived from a string label, an integer index or a pointer. + + Button("OK"); // Label = "OK", ID = hash of "OK" + Button("Cancel"); // Label = "Cancel", ID = hash of "Cancel" + + - ID are uniquely scoped within windows, tree nodes, etc. so no conflict can happen if you have two buttons called "OK" in two different windows + or in two different locations of a tree. + + - If you have a same ID twice in the same location, you'll have a conflict: + + Button("OK"); + Button("OK"); // ID collision! Both buttons will be treated as the same. + + Fear not! this is easy to solve and there are many ways to solve it! + + - When passing a label you can optionally specify extra unique ID information within string itself. This helps solving the simpler collision cases. + use "##" to pass a complement to the ID that won't be visible to the end-user: + + Button("Play"); // Label = "Play", ID = hash of "Play" + Button("Play##foo1"); // Label = "Play", ID = hash of "Play##foo1" (different from above) + Button("Play##foo2"); // Label = "Play", ID = hash of "Play##foo2" (different from above) + + - If you want to completely hide the label, but still need an ID: + + Checkbox("##On", &b); // Label = "", ID = hash of "##On" (no label!) + + - Occasionally/rarely you might want change a label while preserving a constant ID. This allows you to animate labels. + For example you may want to include varying information in a window title bar (and windows are uniquely identified by their ID.. obviously) + Use "###" to pass a label that isn't part of ID: + + Button("Hello###ID"; // Label = "Hello", ID = hash of "ID" + Button("World###ID"; // Label = "World", ID = hash of "ID" (same as above) + + sprintf(buf, "My game (%f FPS)###MyGame"); + Begin(buf); // Variable label, ID = hash of "MyGame" + + - Use PushID() / PopID() to create scopes and avoid ID conflicts within the same Window. + This is the most convenient way of distinguishing ID if you are iterating and creating many UI elements. + You can push a pointer, a string or an integer value. Remember that ID are formed from the concatenation of everything in the ID stack! + + for (int i = 0; i < 100; i++) + { + PushID(i); + Button("Click"); // Label = "Click", ID = hash of integer + "label" (unique) + PopID(); + } + + for (int i = 0; i < 100; i++) + { + MyObject* obj = Objects[i]; + PushID(obj); + Button("Click"); // Label = "Click", ID = hash of pointer + "label" (unique) + PopID(); + } + + for (int i = 0; i < 100; i++) + { + MyObject* obj = Objects[i]; + PushID(obj->Name); + Button("Click"); // Label = "Click", ID = hash of string + "label" (unique) + PopID(); + } + + - More example showing that you can stack multiple prefixes into the ID stack: + + Button("Click"); // Label = "Click", ID = hash of "Click" + PushID("node"); + Button("Click"); // Label = "Click", ID = hash of "node" + "Click" + PushID(my_ptr); + Button("Click"); // Label = "Click", ID = hash of "node" + ptr + "Click" + PopID(); + PopID(); + + - Tree nodes implicitly creates a scope for you by calling PushID(). + + Button("Click"); // Label = "Click", ID = hash of "Click" + if (TreeNode("node")) + { + Button("Click"); // Label = "Click", ID = hash of "node" + "Click" + TreePop(); + } + + - When working with trees, ID are used to preserve the open/close state of each tree node. + Depending on your use cases you may want to use strings, indices or pointers as ID. + e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change. + e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense! + + Q: How can I tell when ImGui wants my mouse/keyboard inputs and when I can pass them to my application? + A: You can read the 'io.WantCaptureXXX' flags in the ImGuiIO structure. Preferably read them after calling ImGui::NewFrame() to avoid those flags lagging by one frame, but either should be fine. + When 'io.WantCaptureMouse' or 'io.WantCaptureKeyboard' flags are set you may want to discard/hide the inputs from the rest of your application. + When 'io.WantInputsCharacters' is set to may want to notify your OS to popup an on-screen keyboard, if available. + ImGui is tracking dragging and widget activity that may occur outside the boundary of a window, so 'io.WantCaptureMouse' is a more accurate and complete than testing for ImGui::IsMouseHoveringAnyWindow(). + (Advanced note: text input releases focus on Return 'KeyDown', so the following Return 'KeyUp' event that your application receive will typically have 'io.WantcaptureKeyboard=false'. + Depending on your application logic it may or not be inconvenient. You might want to track which key-downs were for ImGui (e.g. with an array of bool) and filter out the corresponding key-ups.) + + Q: How can I load a different font than the default? (default is an embedded version of ProggyClean.ttf, rendered at size 13) + A: Use the font atlas to load the TTF file you want: + + ImGuiIO& io = ImGui::GetIO(); + io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels); + io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() + + Q: How can I easily use icons in my application? + A: The most convenient and practical way is to merge an icon font such as FontAwesome inside you main font. Then you can refer to icons within your strings. + Read 'How can I load multiple fonts?' and the file 'extra_fonts/README.txt' for instructions. + + Q: How can I load multiple fonts? + A: Use the font atlas to pack them into a single texture: + (Read extra_fonts/README.txt and the code in ImFontAtlas for more details.) + + ImGuiIO& io = ImGui::GetIO(); + ImFont* font0 = io.Fonts->AddFontDefault(); + ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels); + ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels); + io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() + // the first loaded font gets used by default + // use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime + + // Options + ImFontConfig config; + config.OversampleH = 3; + config.OversampleV = 1; + config.GlyphExtraSpacing.x = 1.0f; + io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, &config); + + // Combine multiple fonts into one (e.g. for icon fonts) + ImWchar ranges[] = { 0xf000, 0xf3ff, 0 }; + ImFontConfig config; + config.MergeMode = true; + io.Fonts->AddFontDefault(); + io.Fonts->LoadFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges); // Merge icon font + io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, NULL, &config, io.Fonts->GetGlyphRangesJapanese()); // Merge japanese glyphs + + Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic? + A: When loading a font, pass custom Unicode ranges to specify the glyphs to load. + All your strings needs to use UTF-8 encoding. Specifying literal in your source code using a local code page (such as CP-923 for Japanese or CP-1251 for Cyrillic) will not work. + In C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax. Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8. + You can also try to remap your local codepage characters to their Unicode codepoint using font->AddRemapChar(), but international users may have problems reading/editing your source code. + + io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese()); // Load Japanese characters + io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8() + io.ImeWindowHandle = MY_HWND; // To input using Microsoft IME, give ImGui the hwnd of your application + + As for text input, depends on you passing the right character code to io.AddInputCharacter(). The example applications do that. + + Q: How can I use the drawing facilities without an ImGui window? (using ImDrawList API) + A: The easiest way is to create a dummy window. Call Begin() with NoTitleBar|NoResize|NoMove|NoScrollbar|NoSavedSettings|NoInputs flag, zero background alpha, + then retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like. + + - tip: the construct 'IMGUI_ONCE_UPON_A_FRAME { ... }' will run the block of code only once a frame. You can use it to quickly add custom UI in the middle of a deep nested inner loop in your code. + - tip: you can create widgets without a Begin()/End() block, they will go in an implicit window called "Debug" + - tip: you can call Begin() multiple times with the same name during the same frame, it will keep appending to the same window. this is also useful to set yourself in the context of another window (to get/set other settings) + - tip: you can call Render() multiple times (e.g for VR renders). + - tip: call and read the ShowTestWindow() code in imgui_demo.cpp for more example of how to use ImGui! + + + ISSUES & TODO-LIST + ================== + Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues + The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point it usually moves to the github) + + - doc: add a proper documentation+regression testing system (#435) + - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass. + - window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis) (#690) + - window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify. + - window: allow resizing of child windows (possibly given min/max for each axis?) + - window: background options for child windows, border option (disable rounding) + - window: add a way to clear an existing window instead of appending (e.g. for tooltip override using a consistent api rather than the deferred tooltip) + - window: resizing from any sides? + mouse cursor directives for app. +!- window: begin with *p_open == false should return false. + - window: get size/pos helpers given names (see discussion in #249) + - window: a collapsed window can be stuck behind the main menu bar? + - window: when window is small, prioritize resize button over close button. + - window: detect extra End() call that pop the "Debug" window out and assert at call site instead of later. + - window/tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic. + - window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd. + - draw-list: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command). +!- scrolling: allow immediately effective change of scroll if we haven't appended items yet + - splitter/separator: formalize the splitter idiom into an official api (we want to handle n-way split) (#319) + - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. + - widgets: clean up widgets internal toward exposing everything. + - widgets: add disabled and read-only modes (#211) + - main: considering adding an Init() function? some constructs are awkward in the implementation because of the lack of them. +!- main: make it so that a frame with no window registered won't refocus every window on subsequent frames (~bump LastFrameActive of all windows). + - main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes + - main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode? + - input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile. + - input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events?

(off #218) + - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725) + - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc). + - input text multi-line: way to dynamically grow the buffer without forcing the user to initially allocate for worse case (follow up on #200) + - input text multi-line: line numbers? status bar? (follow up on #200) + - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725) + - input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position. + - input number: optional range min/max for Input*() functions + - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled) + - input number: use mouse wheel to step up/down + - input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack. + - button: provide a button that looks framed. + - text: proper alignment options + - image/image button: misalignment on padded/bordered button? + - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col.

If you need this, don't upgrade. My + assumption is that almost nobody was doing this, and those who + were will find the built-in SIMD more satisfactory anyway. + + - RGB values computed for JPEG images are slightly different from + previous versions of stb_image. (This is due to using less + integer precision in SIMD.) The C code has been adjusted so + that the same RGB values will be computed regardless of whether + SIMD support is available, so your app should always produce + consistent results. But these results are slightly different from + previous versions. (Specifically, about 3% of available YCbCr values + will compute different RGB results from pre-1.49 versions by +-1; + most of the deviating values are one smaller in the G channel.) + + - If you must produce consistent results with previous versions of + stb_image, #define STBI_JPEG_OLD and you will get the same results + you used to; however, you will not get the SIMD speedups for + the YCbCr-to-RGB conversion step (although you should still see + significant JPEG speedup from the other changes). + + Please note that STBI_JPEG_OLD is a temporary feature; it will be + removed in future versions of the library.

Data read from callbacks are processed +// through a small internal buffer (currently 128 bytes) to try to reduce +// overhead. +// +// The three functions you must define are "read" (reads some bytes of data), +// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). +// +// =========================================================================== +// +// SIMD support +// +// The JPEG decoder will try to automatically use SIMD kernels on x86 when +// supported by the compiler. For ARM Neon support, you must explicitly +// request it. +// +// (The old do-it-yourself SIMD API is no longer supported in the current +// code.) +// +// On x86, SSE2 will automatically be used when available based on a run-time +// test; if not, the generic C versions are used as a fall-back. On ARM targets, +// the typical path is to have separate builds for NEON and non-NEON devices +// (at least this is true for iOS and Android). Therefore, the NEON support is +// toggled by a build flag: define STBI_NEON to get NEON loops. +// +// The output of the JPEG decoder is slightly different from versions where +// SIMD support was introduced (that is, for versions before 1.49). The +// difference is only +-1 in the 8-bit RGB channels, and only on a small +// fraction of pixels. You can force the pre-1.49 behavior by defining +// STBI_JPEG_OLD, but this will disable some of the SIMD decoding path +// and hence cost some performance. +// +// If for some reason you do not want to use any of SIMD code, or if +// you have issues compiling it, you can disable it entirely by +// defining STBI_NO_SIMD. +// +// =========================================================================== +// +// HDR image support (disable by defining STBI_NO_HDR) +// +// stb_image now supports loading HDR images in general, and currently +// the Radiance .HDR file format, although the support is provided +// generically. You can still load any file through the existing interface; +// if you attempt to load an HDR file, it will be automatically remapped to +// LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; +// both of these constants can be reconfigured through this interface: +// +// stbi_hdr_to_ldr_gamma(2.2f); +// stbi_hdr_to_ldr_scale(1.0f); +// +// (note, do not use _inverse_ constants; stbi_image will invert them +// appropriately). +// +// Additionally, there is a new, parallel interface for loading files as +// (linear) floats to preserve the full dynamic range: +// +// float *data = stbi_loadf(filename, &x, &y, &n, 0); +// +// If you load LDR images through this interface, those images will +// be promoted to floating point values, run through the inverse of +// constants corresponding to the above: +// +// stbi_ldr_to_hdr_scale(1.0f); +// stbi_ldr_to_hdr_gamma(2.2f); +// +// Finally, given a filename (or an open file or memory block--see header +// file for details) containing image data, you can query for the "most +// appropriate" interface to use (that is, whether the image is HDR or +// not), using: +// +// stbi_is_hdr(char *filename); +// +// =========================================================================== +// +// iPhone PNG support: +// +// By default we convert iphone-formatted PNGs back to RGB, even though +// they are internally encoded differently. You can disable this conversion +// by by calling stbi_convert_iphone_png_to_rgb(0), in which case +// you will always just get the native iphone "format" through (which +// is BGR stored in RGB). +// +// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per +// pixel to remove any premultiplied alpha *only* if the image file explicitly +// says there's premultiplied data (currently only happens in iPhone images, +// and only if iPhone convert-to-rgb processing is on). +// + + +#ifndef STBI_NO_STDIO +#include +#endif // STBI_NO_STDIO + +#define STBI_VERSION 1 + +enum +{ + STBI_default = 0, // only used for req_comp + + STBI_grey = 1, + STBI_grey_alpha = 2, + STBI_rgb = 3, + STBI_rgb_alpha = 4 +};

In this mode, it declares a +// single public symbol, STB_TexteditState, which encapsulates the current +// state of a text widget (except for the string, which you will store +// separately). +// +// To compile in this mode, you must define STB_TEXTEDIT_CHARTYPE to a +// primitive type that defines a single character (e.g. char, wchar_t, etc). +// +// To save space or increase undo-ability, you can optionally define the +// following things that are used by the undo system: +// +// STB_TEXTEDIT_POSITIONTYPE small int type encoding a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// If you don't define these, they are set to permissive types and +// moderate sizes. The undo system does no memory allocations, so +// it grows STB_TexteditState by the worst-case storage which is (in bytes): +// +// [4 + sizeof(STB_TEXTEDIT_POSITIONTYPE)] * STB_TEXTEDIT_UNDOSTATE_COUNT +// + sizeof(STB_TEXTEDIT_CHARTYPE) * STB_TEXTEDIT_UNDOCHAR_COUNT +// +// +// Implementation mode: +// +// If you define STB_TEXTEDIT_IMPLEMENTATION before including this, it +// will compile the implementation of the text edit widget, depending +// on a large number of symbols which must be defined before the include. +// +// The implementation is defined only as static functions. You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit. This is true for both plain text and +// rich text; even with rich text stb_truetype interacts with your +// code as if there was an array of all the displayed characters. +// +// Symbols that must be the same in header-file and implementation mode: +// +// STB_TEXTEDIT_CHARTYPE the character type +// STB_TEXTEDIT_POSITIONTYPE small type that a valid cursor position +// STB_TEXTEDIT_UNDOSTATECOUNT the number of undo states to allow +// STB_TEXTEDIT_UNDOCHARCOUNT the number of characters to store in the undo buffer +// +// Symbols you must define for implementation mode: +// +// STB_TEXTEDIT_STRING the type of object representing a string being edited, +// typically this is a wrapper object with other data you need +// +// STB_TEXTEDIT_STRINGLEN(obj) the length of the string (ideally O(1)) +// STB_TEXTEDIT_LAYOUTROW(&r,obj,n) returns the results of laying out a line of characters +// starting from character #n (see discussion below) +// STB_TEXTEDIT_GETWIDTH(obj,n,i) returns the pixel delta from the xpos of the i'th character +// to the xpos of the i+1'th char for a line of characters +// starting at character #n (i.e. accounts for kerning +// with previous char) +// STB_TEXTEDIT_KEYTOTEXT(k) maps a keyboard input to an insertable character +// (return type is int, -1 means not valid to insert) +// STB_TEXTEDIT_GETCHAR(obj,i) returns the i'th character of obj, 0-based +// STB_TEXTEDIT_NEWLINE the character returned by _GETCHAR() we recognize +// as manually wordwrapping for end-of-line positioning +// +// STB_TEXTEDIT_DELETECHARS(obj,i,n) delete n characters starting at i +// STB_TEXTEDIT_INSERTCHARS(obj,i,c*,n) insert n characters at i (pointed to by STB_TEXTEDIT_CHARTYPE*) +// +// STB_TEXTEDIT_K_SHIFT a power of two that is or'd in to a keyboard input to represent the shift key +// +// STB_TEXTEDIT_K_LEFT keyboard input to move cursor left +// STB_TEXTEDIT_K_RIGHT keyboard input to move cursor right +// STB_TEXTEDIT_K_UP keyboard input to move cursor up +// STB_TEXTEDIT_K_DOWN keyboard input to move cursor down +// STB_TEXTEDIT_K_LINESTART keyboard input to move cursor to start of line // e.g. HOME +// STB_TEXTEDIT_K_LINEEND keyboard input to move cursor to end of line // e.g. END +// STB_TEXTEDIT_K_TEXTSTART keyboard input to move cursor to start of text // e.g. ctrl-HOME +// STB_TEXTEDIT_K_TEXTEND keyboard input to move cursor to end of text // e.g. ctrl-END +// STB_TEXTEDIT_K_DELETE keyboard input to delete selection or character under cursor +// STB_TEXTEDIT_K_BACKSPACE keyboard input to delete selection or character left of cursor +// STB_TEXTEDIT_K_UNDO keyboard input to perform undo +// STB_TEXTEDIT_K_REDO keyboard input to perform redo +// +// Optional: +// STB_TEXTEDIT_K_INSERT keyboard input to toggle insert mode +// STB_TEXTEDIT_IS_SPACE(ch) true if character is whitespace (e.g. 'isspace'), +// required for default WORDLEFT/WORDRIGHT handlers +// STB_TEXTEDIT_MOVEWORDLEFT(obj,i) custom handler for WORDLEFT, returns index to move cursor to +// STB_TEXTEDIT_MOVEWORDRIGHT(obj,i) custom handler for WORDRIGHT, returns index to move cursor to +// STB_TEXTEDIT_K_WORDLEFT keyboard input to move cursor left one word // e.g. ctrl-LEFT +// STB_TEXTEDIT_K_WORDRIGHT keyboard input to move cursor right one word // e.g. ctrl-RIGHT +// STB_TEXTEDIT_K_LINESTART2 secondary keyboard input to move cursor to start of line +// STB_TEXTEDIT_K_LINEEND2 secondary keyboard input to move cursor to end of line +// STB_TEXTEDIT_K_TEXTSTART2 secondary keyboard input to move cursor to start of text +// STB_TEXTEDIT_K_TEXTEND2 secondary keyboard input to move cursor to end of text +// +// Todo: +// STB_TEXTEDIT_K_PGUP keyboard input to move cursor up a page +// STB_TEXTEDIT_K_PGDOWN keyboard input to move cursor down a page +// +// Keyboard input must be encoded as a single integer value; e.g. a character code +// and some bitflags that represent shift states. to simplify the interface, SHIFT must +// be a bitflag, so we can test the shifted state of cursor movements to allow selection, +// i.e. (STB_TEXTED_K_RIGHT|STB_TEXTEDIT_K_SHIFT) should be shifted right-arrow. +// +// You can encode other things, such as CONTROL or ALT, in additional bits, and +// then test for their presence in e.g. STB_TEXTEDIT_K_WORDLEFT.

Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers.

Thus, anti-aliasing of intersecting shapes may look wrong.

This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since they different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// ADVANCED USAGE +// +// Quality: +// +// - Use the functions with Subpixel at the end to allow your characters +// to have subpixel positioning. Since the font is anti-aliased, not +// hinted, this is very import for quality. (This is not possible with +// baked fonts.) +// +// - Kerning is now supported, and if you're supporting subpixel rendering +// then kerning is worth using to give your text a polished look. +// +// Performance: +// +// - Convert Unicode codepoints to glyph indexes and operate on the glyphs; +// if you don't do this, stb_truetype is forced to do the conversion on +// every call. +// +// - There are a lot of memory allocations. We should modify it to take +// a temp buffer and allocate from the temp buffer (without freeing), +// should help performance a lot. +// +// NOTES +// +// The system uses the raw data found in the .ttf file without changing it +// and without building auxiliary data structures. This is a bit inefficient +// on little-endian systems (the data is big-endian), but assuming you're +// caching the bitmaps or glyph shapes this shouldn't be a big deal. +// +// It appears to be very hard to programmatically determine what font a +// given file is in a general way. I provide an API for this, but I don't +// recommend it. +// +// +// SOURCE STATISTICS (based on v0.6c, 2050 LOC) +// +// Documentation & header file 520 LOC \___ 660 LOC documentation +// Sample code 140 LOC / +// Truetype parsing 620 LOC ---- 620 LOC TrueType +// Software rasterization 240 LOC \ . +// Curve tesselation 120 LOC \__ 550 LOC Bitmap creation +// Bitmap management 100 LOC / +// Baked bitmap interface 70 LOC / +// Font name matching & access 150 LOC ---- 150 +// C runtime library abstraction 60 LOC ---- 60 +// +// +// PERFORMANCE MEASUREMENTS FOR 1.06: +// +// 32-bit 64-bit +// Previous release: 8.83 s 7.68 s +// Pool allocations: 7.72 s 6.34 s +// Inline sort : 6.54 s 5.65 s +// New rasterizer : 5.63 s 5.00 s + +////////////////////////////////////////////////////////////////////////////// +////////////////////////////////////////////////////////////////////////////// +//// +//// SAMPLE PROGRAMS +//// +// +// Incomplete text-in-3d-api example, which draws quads properly aligned to be lossless +// +#if 0 +#define STB_TRUETYPE_IMPLEMENTATION // force following include to generate implementation +#include "stb_truetype.h" + +unsigned char ttf_buffer[1<<20]; +unsigned char temp_bitmap[512*512]; + +stbtt_bakedchar cdata[96]; // ASCII 32..126 is 95 glyphs +GLuint ftex; + +void my_stbtt_initfont(void) +{ + fread(ttf_buffer, 1, 1<<20, fopen("c:/windows/fonts/times.ttf", "rb")); + stbtt_BakeFontBitmap(ttf_buffer,0, 32.0, temp_bitmap,512,512, 32,96, cdata); // no guarantee this fits! + // can free ttf_buffer at this point + glGenTextures(1, &ftex); + glBindTexture(GL_TEXTURE_2D, ftex); + glTexImage2D(GL_TEXTURE_2D, 0, GL_ALPHA, 512,512, 0, GL_ALPHA, GL_UNSIGNED_BYTE, temp_bitmap); + // can free temp_bitmap at this point + glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); +} + +void my_stbtt_print(float x, float y, char *text) +{ + // assume orthographic projection with units = screen pixels, origin at top left + glEnable(GL_TEXTURE_2D); + glBindTexture(GL_TEXTURE_2D, ftex); + glBegin(GL_QUADS); + while (*text) { + if (*text >= 32 && *text < 128) { + stbtt_aligned_quad q; + stbtt_GetBakedQuad(cdata, 512,512, *text-32, &x,&y,&q,1);//1=opengl & d3d10+,0=d3d9 + glTexCoord2f(q.s0,q.t1); glVertex2f(q.x0,q.y0); + glTexCoord2f(q.s1,q.t1); glVertex2f(q.x1,q.y0); + glTexCoord2f(q.s1,q.t0); glVertex2f(q.x1,q.y1); + glTexCoord2f(q.s0,q.t0); glVertex2f(q.x0,q.y1); + } + ++text; + } + glEnd(); +} +#endif +// +// +////////////////////////////////////////////////////////////////////////////// +// +// Complete program (this compiles): get a single bitmap, print as ASCII art +// +#if 0 +#include +#define STB_TRUETYPE_IMPLEMENTATION // force following include to generate implementation +#include "stb_truetype.h" + +char ttf_buffer[1<<25]; + +int main(int argc, char **argv) +{ + stbtt_fontinfo font; + unsigned char *bitmap; + int w,h,i,j,c = (argc > 1 ? atoi(argv[1]) : 'a'), s = (argc > 2 ? atoi(argv[2]) : 20); + + fread(ttf_buffer, 1, 1<<25, fopen(argc > 3 ? argv[3] : "c:/windows/fonts/arialbd.ttf", "rb")); + + stbtt_InitFont(&font, ttf_buffer, stbtt_GetFontOffsetForIndex(ttf_buffer,0)); + bitmap = stbtt_GetCodepointBitmap(&font, 0,stbtt_ScaleForPixelHeight(&font, s), c, &w, &h, 0,0); + + for (j=0; j < h; ++j) { + for (i=0; i < w; ++i) + putchar(" .:ioVM@"[bitmap[j*w+i]>>5]); + putchar('\n'); + } + return 0; +} +#endif +// +// Output: +// +// .ii. +// @@@@@@. +// V@Mio@@o +// :i.
